Fig. 7From: New technique for detecting cracked teeth and evaluating the crack depth by contrast-enhanced cone beam computed tomography: an in vitro studyReceiver operating characteristic (ROC) curves of the two measurements. The blue line represents pre-CBCT, which had good discriminative power with area under the ROC curve (95% confidence interval) of 0.958 (95% CI 0.843–1.074). The red line represents the contrast-enhanced CBCT which had good discriminative power with area under ROC curve (95% confidence interval) of 0.979 (95% CI 0.921–1.037).
